Answer: [tex]v=-\frac{1}{15},\:v=\frac{1}{15}[/tex]
Step-by-step explanation: [tex]-3\left|\frac{1-2}{5v}\right|=-9[/tex]
[tex]-\frac{3}{5\left|v\right|}=-9[/tex]
[tex]-\frac{3}{5\left|v\right|}\cdot \:5\left|v\right|=-9\cdot \:5\left|v\right|[/tex]
[tex]-3=-45\left|v\right|[/tex]
[tex]v=-\frac{1}{15},\:v=\frac{1}{15}[/tex]
